ABSTRACT:
A rolling bearing includes an outer race ring, an inner race ring and a plurality of rolling bodies arranged between the race rings and adapted to roll against race tracks provided in the race ring surfaces facing each other. The bearing further includes at least one member spaced apart from the race tracks and contacting both race rings. The rolling bodies are electrically non-conductive while the at least one member contacting both race rings is highly electrically conductive, thereby allowing the transfer of electrical currents out of the bearing in an unharmful manner and/or the transfer of electrical signals through the bearing for processing outside the bearing.
